a man that likes music but isn't good at playing music. Can be a huge asshole, but will come around to make you kind of happy. Also they're a bit fruity.

Not the best looking person. He will for sure be there for you. No matter what happens. He is very caring and sensitive but doesn’t show it

Your right-hand bro who's always got your back. Most people think that he's little more than some loser that just tags along with you, but you know that he's there to help you out.

Named after the younger brother of the famous Super Mario Brothers.
Person 1 "Dude, who invited the fricken' geek?"

Person 2 "Back off, man; he's my Luigi."

Luigi is the kind of guy who would message you in the middle of the night just to tell you a crazy story that happened to him on that day or just to say that he misses you. He knows the right words to say when you're feeling down and he knows when to shut up when you don't feel like talking. He's the kind of guy who would call you when he's drunk and tell you how an amazing friend you are and how he's lucky to have you. He doesn't care if you eat like a pig or if your hair is all messed up. He doesn't mind if you can't sing. Because he loves you for who you are and not for who you're not. He would stay up late for you when he knows something's wrong and will only sleep if he knows you're okay. He would sit down and play the piano if he doesn't feel like talking or just laugh at everything that's getting out of hand. He's one of a kind and if you have a Luigi in your life, you are truly lucky.

The better yet always ignored of the Mario brothers. He's obviously better, I mean, come on, his brother had to be saved by "scaredy-cat" and the supposedly weak Luigi!
"Thank you, Luigi!" "Finally, peaople see that I'M the star!"

Luigi is your best friend! He's nice to be around, and is super kind. He is an ongoing enthusiastic lovable guy, and is always there when you need him. He's the type of guy you want for a best friend. Luigi is fast, and athletic, and is the kind of inspiration you need. He has the nicest eyes, when he thinks that they're bland, and a playful smile.
He's such a good friend! No wonder his name is Luigi
